Title: Flowmeter
Inventor: SHIRAISHI TAIICHI
IPC: G01F3/10
Filed: 1981-10-17
Abstract: PURPOSE:To smooth the rotating effect of rotors without receiving the effect of gnawing of fine particles and to permit normal flow rate measurement by applying high viscosity liquid contg. fine particles to a special structural body having prescribed recesses. CONSTITUTION:When special liquid such as COM flows into a flowmeter A, a pair of rotors 5 mesh with each other and rotate. The rotors 5 have the shape of a helical gear and fine particles are transferred without gnawing into their tooth parts 7. The confining effect of the measuring liquid generated by the rotation of the rotors 5 and the reverse effect thereof are eliminated by the recesses 8a, 8b formed on the end surfaces on both sides of the rotors 5 and the recesses 9 formed on both sides of a metering chamber 3, whereby the transfer of the high viscosity liquid is smoothed. A piston 14 is forced upward by the pressure difference between the inflow side of the flowmeter A and the inside of a lubricating oil pot 12, by which the lubricating oil is supplied into an oil well 21. This oil acts upon the chamber 3 side through the spacings between rorot shafts 6 and carbon bearings 26 and the slideways of the bearings 26 are maintained always in a smooth condition.

Title: Method for inhibiting continuous transmission on radio device
Inventor: SASAKI SABUROU
IPC: H04B17/00
Filed: 1982-09-24
Abstract: PURPOSE:To prevent a fault due to continuous transmission, by measuring transmission time, and disconnecting a power source supplied to a radio device, when the continuous transmission time exceeds the setting time of a time limiting circuit. CONSTITUTION:A current detecting circuit part 1 is inserted between an input and an output to detect current to be supplied to a load. When a current more than the set value of the detector flows, the detected output is applied to the time limiting circuit part 2. The circuit part 2 discriminates whether the input from the circuit part 1 is continuously applied for a period more than a fixed setting time or not; and when the input from the circuit part 1 is applied more than the setting time, it sends an output to a relay part 3 and a fault displaying part 4. When a relay A is actuated, its contact a2 is closed and held by itself. By the continuous transmission inhibiting method, the fault due to continuous transmission can be prevented without operating the radio device itself during use.

Inventor: ABE HIRONOBU
IPC: G02F1/1333
Filed: 1995-06-30
Abstract: PURPOSE: To suppress the increasing of the impression voltage to electric discharge electrodes and the variation of electric discharge starting voltages. CONSTITUTION: This device is a plasma address display device constituted by laminating electrooptical display cells and plasma cells via a dielectric sheet. Plural anode electrodes 11A and cathode electrodes 11K constituting electric discharge electrodes and extending in a column direction are alternately formed by being kept with a prescribed interval on the main surface of the inside of a glass substrate 10 constituting plasma cells. One pair of electrodes 11A, 11K corresponds to one electric discharge channel. Electrodes 11A, 11K are formed in a state in which they are respectively divided into two parts. Anode voltage is parallel impressed on divided anode electrodes 11A1 , 11A2 and a cathode voltage is parallel impressed on divided cathode electrodes 11K1 11k2 .  Then, since the resistance of electric discharge electrodes is reduced and the voltage equivalent to the resistance drop of an impression voltage becomes small, the increasing of the voltage to be impressed on the electric discharge electrodes is suppressed. Also, the variation of the electric discharge starting voltages in the same line is reduced.
